Your problem is that the image at https://www.ridesmartcotaevents.info/wp-content/login-logo.png unavailable or incorrectly or is protected by security settings of the server. The problem is not in the plugin. Check the server configuration or correct the image. When the image is available at https://www.ridesmartcotaevents.info/wp-content/login-logo.png, then everything will be fine.
